SPECIFICATION forming part of Letters Patent No. 450,364, dated April 14, 1891.

Application filed October 23, 1890- Serial No. 369,063. (No model.)

To aZZ whom, it may concern:

Be it known that I, HUGO COOK, a citizen of the United States, residing at Dayton, in the county of lilontgomeryand State of Ohio, have invented certain new and useful Iniprovements in Cash Registers and Indicators, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification.

My present invention consists, chiefly, in improvements on the machine described in my former patent, No. 445,671, dated February 3, 1891, to which reference may be made for a more detailed description of some of the parts of the machine than will be necessary for the mere explanation of my improvements.

My improvements will be described .in detail, and their novelty pointed out in the claims.

Fig. 18 is aside view of one of the winding ratchets and its operating-pawl when the ratchet is in such position as to render the pawl inoperative.

The working parts of the machine are supported in a suitable frame-work, consisting in this instance chiefly of the side frames A A, the cross-pieces and rods connecting them, and the supplemental side plates 13 B, mounted upon the frames A A and supporting the main portions of the registering mechanism. The front ends of the operating-keys are provided with the usual numbered finger-buttons, and their rear ends rest on the crosspiece 0 of the frame-work and carry the vertically-guided indicatorrods D, which are provided at their upper ends with the usual indicators E. The rods D are provided with collars or projections F, co-operating with the supporting-bar G, to temporarily hold the indicators exposed at a glass-covered window in the upper part of the casing, (not shown,) all in the usual well-known manner.

As in myprior patent before referrel to, the registering-wheel is actuated by a springdriven motor-wheel whose movements are controlled and measured by an escapement mechanism operated by the keys. The motorwheel, under tension of its spring, constantly tends to revolve and is geared directly orindirectly to the registering-wheel, so that whenever the motor-wheel is permitted to revolve it turns the registering-wheel a distance proportionate to the amount of its own movement. The motor-wheel is heldin check and normally prevented from rotating under the influence of its spring by an escapement mechanism interposed between it and the keys, and this mechanism, under the operation of diiferent keys, permits the motor-wheel to rotate different degrees, and to thereby turn the registering-wheel different degrees,

ICO

accordingly as one or another of the keys is operated. There are two of these motor wheels in the machine, one for driving the cent-registering wheel and the other for. the dollar-registering wheel audits connected train of wheels with an escapement mechan-v ism interposed between each motor-wheel and the set of operating-keys corresponding to it. The escapement mechanism-in each case consists of a train of escapement-wheels and a co-operating series of detents, all of which, excepting one, are also preferably supported. on wheels or disks mounted on the same shaft as the escapement-wheels. escapem cut and detent supporting wheels are illustrated and described in detail in my aforesaid patent. general mode of operation are substantially the same in my present machine, so that only such description of them as is necessary to an understanding of the improvements constituting my present invention will be given here. i

The two trains of wheels are shown in Figs. 2, 3, and 11 and details of them in Figs. 12 and 13. A revoluble shaft G, Figs. 1, 2, 3, and 11, is journaled at its right-hand end in the side plate B and at its left-hand end in a bracket H, suitably supported on a crosspiece of the frame-work. Tight upon the shaft G near its right-hand end is the centregistering wheel I, having on its periphery a series of equidistant numbers in multiples of 5 from O to 95, while tight upon the opposite end of the shaft G, justto the left of the bracket H, is a pinion J, meshing with the spring-driven motor-wheel K, loosely mounted on the shaft L. This motor-wheel is impelled by its spring, hereinafter described, to revolve in the direction of the arrow in 'Fig. '2, and to thereby turn the shaft G and wheel I in the opposite direction, assh'own by the arrow on said wheel. The train of escape ment-wheels A, A A A and A and 'the detent-supporting disks B, B B and'l3 co operating with the first four of them, are

mounted on the shaft G between the'wheel I and pinion J. The detent B which co'operates with the escapement-wheel A is not mounted upon a disk, but is securedto the side of the bracket H which supports the end of the shaft G. I

As shown in Fig. 11, the wheel I has a laterally-extended hub or fixed sleeve on its left side. The hub of the escapement-wheel A ismounted and feathered upon this sleeve, so as to to turn with it, but free to slide laterally upon it. The detent-disks B, B B and B are loosely mounted directly on the shaft G, and each of them has'on its left sidea laterally-extending hub or sleeve, upon whichis mounted and feathered one of the escape ment-wheels A A A and A said hubs 'or sleeves filling the spaces between the faces of.

the disks and serving to space them on the shaft G. The detents which cooperate with These trains of I Their construction and Q V Y 4 ing to turn the latter in the same direction, and so on through the entire train of wheels shape shown in Figs. 12 and 13, from which it will be seen that each of them has two contact-facesan outer one a and an inner one a'-'with a lateral passage or slot at between them.

The wheel I, tight on the shaft G, geared to the motor-wheel K, is constantly tending to turn in the direction of the arrow on it and carry with it the escapement-wheel A. This causes one of the teeth of the wheelA'to press against the outer face of the detent on the disk B andtend to turn the disk in the same direction. As the second escapement-wheel A is feathered on the hub of this disk B said wheel A will also be impelled in the same direction, and one of its teeth will be held pressed against the detent on disk B tendto the last escapement-wheel A whose teeth engage the stationary detent B on the bracket H. It will thus be seen that the power of the motor-wheel'K is transmitted through the pinion J shaft G, wheel I, and the connected train of escapement and detent wheels to the last wheel AF, and that the engagement of the latter with the stationary detent B is what 'outer face a of the co-operating detent is moved out of the plane of said outer face and into the plane of the inner face a, and the wheel, being thereby released, is revolved under the in H hence of the spring-motor until its said tooth strikes theinner face a, the wheel I, of course, tu rning with it. When the wheel is slid to the right again, its said tooth is moved out of the plane of the inner face of the detent through the passage a and is thereby entirely freed from the detent, and thewheel I is turned on, by the spring-motor until the next succeedingtooth of the wheel strikes the outer face a of the detent. It will thus be seen that in orderto let a tooth of an escapement-wheel pass its co-operating detent to permit the wheel to turn a distance equal to that between two of its teeth the wheel is first slid to the left to free its engaged tooth fromthe outer face a of the detent and is then moved to the right again to free fit from the inner face a of the detent.

Owing to the fact that the power of the motor constantly tends to turn the shaft G and wheel 'I'in the direction of the arrow on the latter, and thereby holds the escapement-wheels all pressed against the outer faces of their cooperating detents, when any escapementwheel is released from its detent,in the manner described, the spring-motor turns the wheel I, through the medium of the pinion J and; shaft G, until the next succeeding tooth of" the escapement-wheel engages and is ar- IIO rested by its cooperating detent. v

bers of teeth and are assigned different values. Thus the wheel A on the left has twenty teeth and is called the five-cent wheel. When it is slid to the left and back to the right again, to permit one of its teeth to pass its co-operating detent B itis turned one-twentieth of a complete revolution, and the shaft G and wheel I are turned an equal distance and five cents is registered on the wheel I. The wheel A has only ten teeth, so that when it is moved to the left and back to the right, to permit one of its teeth to pass its co-operating detent on the wheel 13*, it is turned one-tenth of a revolution and the shaft G and wheel I a like distance. So the wheels A and A each have five equidistant teeth and turn one-fifth of a revolution and register twenty cents on the wheel I whenever either is operated to permit one of its teeth to pass its co-operating detent, while the wheel A has only two teeth and is turned a halfrevolution and registers fifty cents on the wheel I at each operation.

The above-described operation of the escapement and detent wheels is substantially the same as that described in my aforesaid patent. The devices interposed between the operating-keys and the esoapement-wheels for giving the latter the right and left movements to free their teeth from their detents, in the manner described; are also the same as those described in my former patent. In brief, they consist of a series of slides 1, 2, 3, 4, and 5, carried in a slide-box M, supported by the frame-work, Figs. 2 and 3, and connected to the escapemcut-wheels by centrally-pivoted levers (3, 7, 8, 9, and 10, flexibly joined to the slides at their lower ends and having forked upper ends engaging peripheral grooves in the hubs of the escapementwheels. The lower side of the slide-box .M is provided with a vertical slot immediately above each key, and each slide has portions of its under side cut away to form pendent lugs, there being one lug for each key, with which the slide co-operates. The lugs on the slides project from the right into the slots immediately above the respective keys with which theyco-operate, as shown in Fig. 3. Each key has on its upper side, immediately beneath its corresponding slot in the box M, a wedge N, Figs. 2, 4, and 5, which enters the slot in the box whenever the front end of the key is depressed and its rear end elevated. The wedge of the key has its bevel on its right side, so that when the wedge of the key enters the slot in the box it will push to the right any slide whose lug projects into the slot, but will not move those slides whose lugs do not project into such slot. IVhenany slide is moved to the right in this manner, it will throw the upper end of the centrally-pivoted lever connected to it to the left, and thereby move the escapement-wheel to the left and free its engaged tooth from the outer face of its co-0pcrating detent. IVhen the key is released and its wedge withdrawn from the slot in the box and the slide is returned to the left by means hereinafter described, the escapeinene wheel is thrown to the right again, its engaged tooth freed from the inner face of the detent, and the wheel permitted to turn until its next succeeding tooth engages the outer face of the detent. The arrangement of the lugs on the slides is such that the wedge of each key will move just the slide or slides which are necessary to operate the proper escapement wheel or wheels to register the value of the key. Thus the slide 5 is the only one whose lug projects into the slot in the box M, which is immediately above the five-centkey, so that when the five-cent key is operated and its wedge enters the slot in the box M the slide 5 will be the only one moved by it. This slide, through the medium of the pivoted lever 10, will operate the escapement-wheel A to permit one of its teeth to pass the detent B and the shaft G and wheel I to be turned one-twentieth of a revolution to register five cents. The slide a will be the only one projecting into the slot above the ten-cent key, so that upon operating that key the escapement-wheel A will be so moved as to permit one of its teeth to pass the detent on the wheel B and the wheel I to be turned onetenth of a revolution. The slides l and 5 will both project into the slot above the fifteencent key, so that the escapement-wheels A and A will both be moved to permit one tooth of each to pass its eo-operating detent and to thereby permit the wheel I to be turned both a tenth and atwentieth of a revolution to register fifteen cents. In like manner the slide connected to the escapement-wheel A projects into the slot over the fifty-cent key, while the slides 1, 2, and 5, connected to the escapement-wheels A, A and A, projectinto the slot overthe seven ty-five-cent key, so that upon the operation of the latter key a tooth on each of those wheels will pass its co-operating detent, and the wheel I will be turned a distance equal to the sum of a half, a fifth, and a twentieth of a revolution to register seventy-five cents, and so on, the combinations being such that each key will move the proper slides to effect the registration of its value on the wheel I, all in the manner and by the means described in my aforesaid patent.

\Vhile both in this case and in my former patent the cent-registering wheel I is secured on the shaft G and geared to the motor-wheel through the medium of said shaft and the pinion J, it is evident that such an arrangement is merely a convenient and not an essential one, for the wheel might have a separate support and be independently geared directly or indirectly to the motor-wheel.

The train of dollar-registering wheels are mounted on a shaft G, Figs. 2, 3, 4, 5, and 11, in line with the shaft G and supported at its left-hand end in the side plate 13 and at its right-hand end in a bracket II, supported on the same cross-piece of the frame-work which carries the bracket H. Tight upon the righthand end of the shaft G just to the right of the bracket H is a pinion J, meshing with a spring-driven motor-wheel K, loose on the shaft L and corresponding to the motor-wheel K of the cent-registering mechanism. The

- spring acting on this motor-wheel tends to rein the opposite direction.

volve it in the direction of the arrow in Fig. 2, and to thereby turn the pinion J" and shaft G Tight upon the opposite end of the shaft G. is a hub having. a laterally-extending integral sleeve 1, upon. which is feathered the first of the escapementwheels 0. The teeth of this wheel co-operate with the adjacent detent-supporting wheel D, which fits against the right-hand end of the sleeve 1 and is loosely mounted directly on the shaft. This wheel D has a laterally extending hub or fixed sleeve on its right side, and on this sleeve is feathered the second escapement-wheel 0 whose teeth co -,operate with the detent-supporting wheel D which in turn has an extended hub, upon which is feathered the third escapementwheel 0 The teeth of this wheel co-operate with the. detent-supporting wheel D upon whose hub is feathered the fourth escapement-wheelC The teeth of the wheel 0 co-operate with the detent on the wheel D The wheel D is loose on the shaft G and has rigid with it on the same hub or sleeve a fifth escapement- Wheel 0 The teeth of the latter co-operate with detents on the opposite ends of a curved rocking arm 0, Figs. 3, 4, 5, and 11, on the end of a rock-shaft P, journaled at its opposite ends in the brackets H 11, Fig. 3. Tight upon one end of a sleeve Q, loose upon this rockshaft P between the brackets H and H, is a pinion R, meshing with the motor-wheel K. Tight upon the opposite end of the sleeve Q is a pinion S, meshing with the primary wheel of the series of total-registering wheels, hereinafter described. One. of the teeth of the escapement-wheel C is normally in engage.- ment with one of the detents on the. rocking arm 0, the detents on the latter serving to hold the train of wheels from turning under the impulse of the motor, as doesthe stationary detent B in the case of the cent-registering train of wheels. Inasmuch asv the wheel 0 is normally held stationary and the wheel D is rigidly. secured to it, the detent on the wheel D is really the end of the train of escapements and detents and serves the, same purpose as the fixed detent B of the cent train of wheels.

Whenever one of the escapement-wheels is moved to the right to disengage its tooth from the outer face of its co-operating detent and then back again to the left to disengage said tooth from the inner face of said detent, the wheel is allowed to turn under. the influence of the motor-wheel until its next succeeding tooth engages the outer face of the detent. This permits the motorwheel to turn the pinion R, and consequently the pinion S and the primary wheel of the total registry, the same part of a revolution that the escapement- 'wheel has turned. ithe motor-wheel K is constantly tending to .turn the pinion J and shaft G, but is held in restraint by the detent on the wheel Di, 1 which latter is held stationaryby the detents ion the rocking arm 0 engaging a tooth of the escapement wheel 0 spring is thus transmitted from the motorwheel through the shaft G tothe sleeve tight ltwill be understood that The power of the on its left-hand end and thence back through the train of escapement and detent wheels to the wheel 0 which is held from turning by the detents on the arm 0. This causes one tooth of each escapement-wheel to be constant-ly pressed against the outer face of its vco-operating detent, so that when any one of said wheels is slidto the right and back to the left again one of its teeth passes the detent and the wheel turns. a part of a revoluthat described-in my former patent, about the only difierence being that in the present case themotor-wheel K is geared to the primary Wheel of the total registry independently of the revoluble shaft upon which the escapement and detent wheels of the dollar series are mounted. In my former patent the primary registering-wheel is geared to a pinion on this shaft.

The first improvement to be now described relates to the transfer mechanism between the cent and dollar registering wheels, whereby the complete revolutions of the cent-wheel are transferred to and registered upon the dollar-wheel. This mechanism is'shown in Figs. 2, 3, 4, 5, and 11. Upon the rock-shaft P, just to the right of the pinion S, is rigidly secured a pendent arm T, whose lower rear end is pressed by a spring against the periphery of what I term a cam-disk U, secured to the inner side of the motor-wheel K, Fig. 15. The periphery of this disk is divided into six spaces of equal. length, and in each alternate space the periphery is cut away, so as to form three raised spaces and three depressed spaces. These spaces are of such length and the numbers of teeth in the gear of the motor-wheel and in the pinion J are such that the periphery of the motor-wheel and disk U moves the distance of one of the spaces while themotor-wheel is turning the pinion J, and consequently the shaft G and wheel I, one complete revolution. As illustrated in the drawings, there are-ninety teeth in the gear of the motor-wheel and fifteen in the pinion J, while the periphery of the disk U is divided into six spaces. Inasmuch as the lower rear end of the arm T is constantly pressed by its spring against the periphery of the disk U it will at times rest in the depressed spaces and at other times on the raised spaces. As the motor-wheel and disk revolve and the end of the arm T drops into one of the depressed spaces, it rocks its shaft P in one direction, and when, by the further revolution of the wheel and disk, it is raised out of the depressed space onto a raised space it rocks its shaft in the opposite direction. This rocking of the shaft P also rocks the arm 0 on its opposite end and throws first one detent and then the other into engagement with the escapement-wheel C At each rocking of the arm 0 one tooth of the wheel is released and this permits the spring impelled motor-wheel to turn the pinion J, shaft G, and the train of wheels on the shaft until the wheel 0 is arrested by another of its teeth engaging the opposite detent on the arm 0. The turning of the motor-wheel not only turns the pinion J,but also the pinions R and S on the sleeve Q, and the primary wheel of the total registry which meshes with the pinion S. The number of teeth on the escapement-wheel O and in the pinion R and the gear of the motor-wheel are relatively such that uponeaeh of these operations consequent upon the rocking of the shaft P the primary wheel of the total registry is turned just far enough to cause one dollar to be added on said registry. My invention, so far as this transfer mechanism is concerned, is not limited to the details of construction and arrangement of the parts, the only essentials being the rocking arm 0, having the detents at its ends and rocked at regular intervals in the revolution of the motor-wheel K and the escapement-wheel C co-operating with said detents and geared to the motor-wheel K. So far as the transfer mechanism alone is concerned the wheel 0 might be tight on the shaft G or mounted on an independent support and geared directly to the motor, for it is evident that its function as part of the transfer mechanism has nothing whatever to do with its co-operation with the other Wheels mounted on the shaft. So far as those wheels are concerned the detent on the wheel D corresponds to the fixed detent B of the cent train of wheels. If the wheel D" were made stationary, the escapement-wheel 0 could be removed from the shaft and the operation of the machine by the dollar-keys would remain precisely the same. It will therefore be understood that so far as the transfer mechanism is concerned the escapement-wheel 0 need not be geared to the motor-wheel K indirectly through the train of wheels connecting it to the shaft G, but might be independently supported and geared directly to the motor-wheel.

Again, while I have shown and described the cam-disk U on the motor-wheel K as the means for rocking the shaft P and arm 0 at regular intervals in the revolution of the wheel K to alternately engage the detents at the opposite ends of the arm 0 with the escapement-wheel, yet I do not wish to be limited to such means for actuating the arm 0, for my invent-ion contemplates, broadly, the combination of the two motor-wheels, the arm 0, having the detents at its opposite ends and rocked at regular intervals in ihe revolution of the wheel K by any suitable means, and the escapement-wheel C co-operating with the detents at the ends of the arm 0 and connected or geared directly or indirectly, to the motor wheel K. Even when a camdisk is employed for rocking the shaft P and arm 0 it need not be secured to the motor wheel K, but may be independently supported and geared directly or indirectly to the wheel K, so as to be revolved by or withit.

Again, under the construction I have shown and described the arm 0 is rocked to release one tooth of the escapement-wheel C only at each complete revolution of the cent-registering wheel; but it is evident that if said wheel were arranged to register a dollar at each halfrevolution the cam-disk could be constructed to rock the arm 0 at each of such half-revolutions to transfer a dollar to the total registry.

The next feature of my invention relates to the method of winding the springs which drive the motor-wheels and regulating the tension thereof, and is illustrated most clearly in Figs. 2, 4, 14, and 15. Both springs are alike in their relative location and arrangement, and I will first describe that employed for driving the motor-wheel K, 4 and 14. A coiled springV is inclosed in a casing WV, secured upon the side of the motor-wheel. The inner end of the spring is secured to a sleeve X, loose on the shaft L, which supports the motor-wheel, while the outer end of the spring is secured to the inner side of the rim of the casing W, and the spring is so arranged that it will be wound up by turning the sleeve X in the direction of the arrow and will tend to turn the motor-wheel K in that direction. The sleeve X projects through the casing IV and just outside the latter has secured on it a ratchet Y, Fig. 4, having in this instance six teeth. The motor-wheel K has secured to it a like spring-casing W, Fig. 15, (slightly different in appearance, owing to the cam-disk U being formed integral with it,) containing a like coiled spring secured at its outer end to the casing and at its inner end to a sleeve loose on the shaft L and carrying a ratchet Y just outside the casing, as in the case of the motor K. Carried by or integral with a sleeve Z, Figs. 2 and 4, loose on the shaft L, between the ratchets Y and Y, is a rearwardly-extending arm or plate Z. In a housing formed of a recessed plate Z secured upon the upper side of the plate Z, Figs. 2 and 4, are confined two sliding pawls Z Z*, Figs. 2, 4, and 17. Spiral springs IIO ' bar E Figs. 4 and 5, extending across and resting upon the upper sides of the operating-keys and hung at each end by side arms E E upon pivotal supports on the framework at b 1), Figs. 1, 4, and 5. It results from this construction and arrangement of the, parts that when the finger-button on the front end of any key is depressed and the rear of thekey is lifted the bar E and link E lift the plate Z and cause the pawls Z and Z to turn the ratchets Y Y and wind up the springs.

Owing to the fact that the motor-wheeltu rns different distances upon the operation of keys of different values the springs are unwound more or less each time, according to the value of the key operated. Thus upon the opera,- tion of the five-cent key the motor-wheel K will move only a veryshort distance, while upon the operation of the seventy-five. or the ninety-five cent keys it will turn much farther. It is therefore necessary that the spring for each motor should be kept wound up sufficiently to turn the motor far enough to re,, ister the value of the highest key in its series; but if the ratchet were turnedand the spring wound an equal distance at each operation of any of the keys the spring would soon become wound up tight if the keys of lower values. should be successively operated and the ma; chine would become locked. To obviate this difficulty in my patent before referred to, the outer end of the spring wasshown as atta hed to a friction-ring fitting the inside of the rim of the casing.

the spring reached a certain limit the ring would slip in the casing and relieve the spring; In the present case I accomplishthesaine result in a more efficient manner and by err-.-

tirely different means. Engaging the for. ward face of the ratchet Y, as seen in Figs.- 2 and 4, is a hooked holding-dog F. The lower end of this dog is pivoted to a short arm F pivoted between ears upon the underside of a cross-piece F of the frame-work. The dog F is therefore free to move upward and downcombined with them a dog G and a spring corresponding to F in the same manner as the motor- K and ratchet Y. This feature of 5 my invention, in its broader scope, contemplates, broadly, the combination of the motor- 5 spring and a tension-regulating spring co-opward, its movements being limited by the engagement of the front and rear portions of the arm F with the under side of the cross-piece. F Secured upon the upper side of the crosspiece F is a strong flat spring F Fig. 4, whose rear end bears upon a pin on the side of the dog F in such manner as to not only hold the, dog in engagement with the ratchet but also to press it downward and pull the ratchet forward against'tho tension of the coiled spring V inside the casing WV, Fig. 14, which tends to turn the ratchet backward. The relative strength of the two springs F and V is such that when the latter is wound up until its ten- This ring was, held against the casing by friction, and when the tension of sion passesa certain degree it will overcome the pressure of the spring F on the dog F and turn theratchetY backward aslightdistance, pulling the dog F upward. The result 0t this backward movement of the ratchet is to bring the points of its teeth into such position that the pawl Z carried by the plate Z, will in its lowest position rest just above and upon the point of the tooth adjacent to it, as

shown in Fig. 18, instead of catching under it, as in Fig. '4. When a key is operated and the bar E link E, and plate Z are lifted, the pawl Z will ride idly over the face of the tooth and not turn the ratchet; or if the stroke of the key gives it sufficient movement -it may engage the next tooth above it and turn the ratchet slightly, but it cannot turn .it far enough to cause a fresh tooth to be caught by the dog F, so that when the key "is released the ratchet turns backward again.

If the operated key, when the parts are in the position just described, is one of the higher values, the motor-wheel may turn far I enough to unwind the spring V and relieve its, tension sufficiently to permit the spring F to again overcome it and pull the ratchet slightly forward against the tension of the spring V, so that when the pawl Z returns to normal position it will catch under a fresh tooth offtheratchet, and upon the next operation of a key will turn theratchet and wind up the spring again. If the. operated key be one of lower value, it may not allow ratchet forward, in which event the ratchet will remain stationary during the succeeding operation of the keys until the motor has moved far enough to produce that result.

When the keys of higher value are successivelyoperated,themotormovesfarenough each time to cause the pawl to turn the ratchet and wind up, the spring frequently; but when the keys of lower value are operated the mo- 1 ton moves, a less distance and the pawl turns the. ratchet less frequently. action of the spring F causes the motorspring. to be maintained at the proper tension 1 to always insure its turning the motor-wheel l the full distance necessary to register the Value of any operated key.

In any event the The motor-wheel K and ratchet Y have erati tg with each other in the manner described without regard to the form of either of them or of their associated parts, or of the I particular manner of combining them. In a somewhat more restricted scope it contemplates the broad combination of a motorspring, a winder therefor, and a tension-regulating spring normally overcoming the tension of the motor-spring,but capable of being overcome by the motor-spring when the latter is wound beyond a given point to render the winder inoperative.

Another feature of myinvention relates to the means for resetting the slides in the slidebox M after they have been shifted by the wedges on the keys entering the slots in the box and after the latter have been withdrawn therefrom. In my former patent two forms of devices for this purpose are described, one consisting simply of flat springs bearing against the outer ends of the two sets of slides and pressing them inward and the other consistin g of cam-wedges engaging the outer ends of the slides, said wedges being lifted upon the operation of a key to permit the slide or slides moved bythat keyto bethrown outward, and falling upon the release of the key to force the slide or slides inward. In my improved construction the slides are reset by the positive movement of resetting-plates which force the slides inward upon the release of an operated key. These resetting-plates H H are shown in Figs. 2, 3, at, and 5. They are in this instance pivotally hung at their upper ends between lugs c 0 upon the inner faces of the side plates B B of the frame-work, Figs. 2 and 3, and their lower inner faces rest against shoulders c 011 the upper sides of the slides near their outer ends. The plate H at the right side of the machine bears against the slides 1, 2, 3, 4, and 5 of the cent series, while the plate H in the left side of the machine bears against the slides of the dollarseries. Flexibly connected to each of the plates H 11 near its middle is a rearwardlyextending rod 1 1 the rear ends of the two rods being connected to the upper side of the vibrating cross-bar E before described, near its middle at cl, Figs. 1, 4:, and 5. lVhen the vibrating bar E is lifted by the operation of a key, the point at is brought nearer the plates ll H than it is when the bar is at rest and the rods 1 1 swing the plates H H outward or permit the slides moved by the operated key to push them outward. hen the operated key is released, the resetting of the bar E causes the rods 1 l to pull the plates inward again and reset the slides, as will be readily understood. This feature of my invention is not restricted to the form of the plates or the method of supporting them, it being sufficient that they are capable of the necessary movements to permit the operation of the slides by the keys and to reset them after the operated key or keys are released and are so cenneetedwith the vibrating bar common to the series of keys as to be given their resetting movement by it.

I The next feature of my invention relates to the train of Wheels constituting the total registry, and more particularly to the transfer devices between said wheels, the locking devices for one set of them, and the means for resetting the wheels to zero. A top plan view of these wheels and the frames in which they are carried is shown in Fig. 2, a frontview at an angle in Fig. 6, a vertical section in Fig. '7, a a side elevation in Fig. 5, a sectional side elevavation in Fig. 4;, and details in Figs. 8, 9, and 10. The upper set of wheels L, L L and L, suitably separated by their hubs on fixed sleeves, are loosely mounted on a shaft J supported in a frame J carried upon the front side of the cross-piece F of the main frame-work of the machine. The frame consists, chiefly, of its two opposite side plates and the front and rear cross-plates uniting them, (see Fig. 16,) by the rear one of which cross-plates it is secured to the cross-piece F of the framework, Fig. 5. The first of the upper set of wheels L is a simple pinion and meshes with the pinion S on the sleeve 0, loose on the rock-shaft P and carrying the pinion R, meshing with the motor-wheel K, as heretofore described. I have referred to this pinion L as the primary wheel of the total registry, since it is through this wheel that the movements of the motor-wheel K are communicated to the rest of the wheels of the total registry. Each of the other wheels L L and L of the upper set consists of a pinion similar to L, but having a wider face, and

carries on its right-hand side a star-toothed wheel (1, Fig. 8, for a purpose hereinafter explained. Fitting between the side plates of the frame J is a rocking frame or cradle J (see Figs. 16, 6, and 7,) loosely mounted on a shaft J supported at its ends in the side plates of the frame J This swinging frame J consists of its two side plates and the cross-bars d (Z uniting their front and rear ends. Pivoted by side arms (i between ears (1 on the upper rear edge of the side plates of the frame J Fig. 1c, is a locking-bar J, having a sharp lower edge, as seen in Fig. at. The bar J is provided with a handle d. lVhen the bar is in its normal position, its lower edge is immediately above the pinions L, L L and I." of the upper set, and the lower rear ends of its side arms (Z fit in notches on the upper side of the rearcrossbar 61 of the swinging frame J" and lock that frame from movement, as seen in Fig. 16. \Vhen the handle d is pulled forward, the lower edge of the bar J is thrown downward and fits between the teeth on the pinions beneath and locks them from movement. At the same time the rear ends of its arms (1" are thrown up out of engagement with the cross bar (1 of the frame J, and the latter is free to rock on its pivotal shaft Jflits rear end rising and its front end falling. Its rear endin rising moves its cross-bar (Z in front of the lower ends of the side arms d of the locking-bar J so that said bar cannot be thrown upward again and the pinions freed until the frame I is restored to normal position, as will be understood from Fi 16. It will thus be seen that when the frame J is in its normal position it is locked by the arms cl of the bar J, and that when the latter is moved into engagement with the pinions the frame J is released and in turn locks the bar J so that the latter cannot be moved to release the pinions until the frame J is restored to normal position, all for a purpose hereinafter explained. The rear cross-bar d of the frame J also has a sharp upperand forward edge which engages and locks the pinions when the front endof the frame J 4 is lowered, so that upon pulling forward the handle of the locking-bar J the pinions are first locked by said bar and then by the bar (1 of the frame J Supported in upwardlyextending ears on the side plates of the frame J is a revoluble shaft J whose outer ends project out through circular openings ff in the side plates of the frame J as shown in Fig. 7. Loosely mounted upon the shaft J are the train of registeringwheels M M M M of the lower set. Each of these wheels of the lower set is composed of several wheels and disks integral wit-h each other or rigidly secured together. The central portion constitutes the registering-wheel proper'andbears on its periphery a series of numbers in multiples of one, from 0 to 9, inclusive. To the right side of the central portion of the wheel is secured a pinion e, and to the left side two disks 6 e the inner one 6 being in this instance of smaller diameter than the outer one and having a notch 6 cut in its periphery at one point, Fig. 8. The disk a has a tooth e projecting from its periphery opposite the notch c in the disk c The pinion e of the right-hand one of the wheels M normally meshes with the pinion L, which constitutes the primary wheel of the series and meshes constantly with the pinion S on the sleeve Q, geared to the motorwheel K, so that the movements of the motor are transmitted directly to the wheel M and the latter is turned at each operation of akey adistance sufficient to register its value. Likewise it is turned one number every time the transfer mechanism between the cent and dollar trains of wheels is actuated by a complete revolution of the cent-registering wheel, in the manner heretofore described.

The pinion secured to the right side of the wheel M normally meshes with the pinion L of the upper train of wheels. secured to the left side of the wheel M, is also in line with the pinion L and at each complete revolution of the wheel M its tooth e turns the pinion L and moves forward one number the wheel M whose pinion e as before stated, meshes with the pinion L In like manner at each complete revolution of the wheel M its toothed disk e will turn the pinion L and move forward the wheel M one number, and so on to the end of the series, thus adding on the wheels M, M M and M the total registration, not only of the dollarkeys,'but also all the dollars registered by the revolutions of the cent-wheel, the remaining amount, less than a dollar, appearing upon the cent-Wheel.

For the purpose of locking the wheels'L,

The disk 6 L L and L at all times, excepting at the moment they are being turned by the co-opcrating single-toothed disks a on the wheels of the lower set, I provide a series of lockingpawls 0', Figs. 4, 6,'and S, strung upon the pivotal shaft J of the frame J one for each of the first three wheels of the lower set and the co-operating wheels L L and L of the upper set. The inner disk 6 on the left side of each wheel of the lower set is arranged in the same plane as the star-toothed wheeld. of its co-operating wheel in the upper set. One of the locking-pawls O, as shown in'Figs. 4 and 8, extends up between each of the disks 6 and its adjacent star-toothed wheel d. A point on the forward side of the upper end of the pawl normally rests on the periphery of the disk e and holds its rear rounded side between two of the teeth on the wheel (1', thereby locking said wheel and the pinion to which it is secured from movement. When, however, the wheel to which the disk c is socured (not shown in Figs. 4 and 8) completes a revolution and the tooth on its disk e engages the co-operating pinion of the upper set, the notch e in the disk e which is opposite the tooth on the disk 6 is brought under the point on the forward side of the pawl O, which allows the pawl to fall or be moved away from the star-toothed wheel cl, so that the tooth on the disk e may turn the pinion to which the wheel d is secured and cause it to turn forward one number the next wheel in the lower set. As the disk e moves on, its notch e is carried from under the point of the pawl, and the rear rounded face of the latter is forced back between two of the teeth on the wheel (1' and locks said wheel and its pinion, as before.

When it is desired to turn the wheels M, M M and M back to zero, as at the end of a days'business, when the amount registered on the wheels has been noted and the machine is to be set for another days business, the handle d of the locking-bar J 6 is pulled forward, thereby throwing the lower edge of the bar into engagement with the pinions L L &c., and locking them, and at the same time releasing the rear cross-bar d of the frame J The front end of this frame is now thrown downward, a handle f Figs. 6, '7, and 16,

formed integral with one of its side plates,

being provided for this purpose. The downward movement of the front end of the frame The wheels M but in my present application I have illustrated means for resetting them by a single revolution of the shaft upon which they are mounted:

As shown in Fig. 7, the left side of each of the wheels M, M M and M has a circular two sets of wheels into gear again.

recess g about the shaft J and projecting into the recess from its inner side in line with the shaft is a short pin or projection g. The shaft J is provided with a series of co operating pins g one in each recess, but near the outer side thereof when the shaft is in its normal position and hence out of the path of travel of the pins g. When the shaft J 7 is slid to the right, however, the pins g on the shaft are brought into the same vertical plane as the pins g, so that if the shaft is revolved its pins will engage the pins g and pick up the wheels and cause them to turn with the shaft. (This much of the resetting mechanism is old and not of my invention.) The left-hand end of the shaft J T is screw-threaded and has a nut K on it, and between this nut and the adjacent side plate of the frame J is confined a spiral spring K which presses the nut K and shaft J to the left. The opposite end of the shaft J extends through. the side plate B of the machine, havinga flexible joint interposed in it at K to accommodate it to the movements of the swinging frame J. On its outer end is a t-hu mb-pieee K, by which it may be turned. When the frame J" is up and the pinions of the lower wheels are in mesh with those of the upper set, the flanged base of the nut K does not coincide with the circular openingf in the side plate of the frame J so that the shaft J cannot be pulled to the right to bring its pins g into line with the pins g in the recesses in the hubs of the wheels; but when the frame .l is thrown down to permit the wheels to be reset to zero the flange of the nut may be drawn into the openingfas the shaft J is pulled to the right. The moving of the shaft J T to the right disengages a notch K in its thumb-piece K from a pin K on the outer side of the plate B. The thumb-piece and shaft may then be turned forward, picking up and turning the wheels with them, and just as the wheels reach zero the notch K will be brought into line with the pin K again and the spring K will snap the shaft back to the left, leaving all the wheels at zero. Upon throwing up the frame J" by means of the handle f the pinions of the wheels in the lowerset are brought into mesh with those of the upper set again, and the machine is ready to begin another days operations. After the wheels have been reset to zero it is necessary that the frame J be thrown up again and the pinions of the lower wheels brought into mesh with those of the upper set, as above described, before any of the keys of the machine are operated, for inasmuch as the pinions of the u pperset of wheels are locked from movement by thelocking-bar J and rear cross-bar d of the frame J 4 during the whole time the latter is down the motor-wheels could not move and the values of the keys operated would not be registered; but the proprietor or party taking off the registry of the machine and resetting the wheels to zero is liable to forget to throw up the frame J" and bring the l have therefore provided a locking device which automatically locks the entire machine from operation as soon as the frame J is thrown down, holds it locked so long as the frame remains down, and automatically unlocks the machine and permits the keys to be operated as soon as the frame is thrown up and the two sets of wheels brought into gear with each other again. This locking device is an exceedingly simple affair, both in construction and mode of operation, and is shown in Fig. 5. It consists of a bell-crank arm 0 hung loosely on the shaft L, which supports the motor-wheels. Its lower vertical arm is normally pulled rearward by a spiral spring 0 so that its lower end hangs immediately in rear of and above the flange on the lower rear side of the vibrating bar 1 which extends across and rests upon the upper sides of all the keys. The front end of the upper horizontal arm of the bell-crank rests upon a rearward extension of one of the side arms d of the looking bar J 6 above described. \Vhen said bar is thrown downward into engagement with the pinions L L (be, the rear extension of its arm d is thrown upward. This lifts the front end of the horizontal arm of the bell-crank and throws the lower end of its vertical arm forward over the flange on the vibrating bar E so that said bar is thereby held from upward movement and locks all the keys of the machine from operation. lVhen it is remembered that the throwing down of the frame J after it has been released by the arms (Z of the bar J, locks said bar 5 and prevents its being moved upward again until the frame J" is again thrown upward and the pinions of the two sets of-wheels brought into nieslnitwill be readily seen that the whole machine is effectually locked so long as the frame J remains down and the wheels are out of gear with each other. lVhen the frame is thrown up again and the bar J moved up to release the pinions of the upper set, the rear extension of the arm (1 is thrown downward and the spring 0 pulls the vertical arm of the bell-crank O rearward and releases the bar and the operating-keys.

The locking device I have just described is a simple, convenient, and effective one for the purpose; but this feature of my invention is not restricted in its broader scope to any particular form and arrangement of lock for the purpose described, but contemplates broadly the combination of a registeringwheel, its prime mover as a driving-pinion, from which it may be disengaged,and a lock of any sort which automatieallylocks the machine from operation when the registeringwheel is disengaged from the driving-pinion or prime mover.

Again, whileI have described a lock which operates automatically to lock the keys upon the disengagement of the registering-wheels from their driving-pinions, yet, as has heretofore been explained, the essential thing is that the machine shall be locked when registering-wheels are disengaged from their drivirig pinion or pinions, so that during the time they are disconnected from the operativeparts of the machine it will be impossible to operate any keys and lose the registry of their values. It is therefore evident that while an automatic lock is the most convenient and desirable, yet a hand-lock might be provided and placed under the control of the registering wheel or wheels in such manner that the latter could not be disengaged from their driving-pinion until said lock had been operated to lock the keys. For instance, in the machine described in this application a very simple locking device might be interposed between the rocking frame J which carries the registering-wheels, and the vibrating bar E overlying the keys, so that when the device was operated to lock the keys the frame would be unlocked and when it was operated to lock the frame the keys would be unlocked. The broad scope of my invention contemplates all such contrivances as these, for it-is evident that whether or not they are as convenient and desirable as an automatic lock, they still perform the essential duty of such lock and accomplish the same important and desirable resultviz., they look the keys when and while the registry of the machine is disconnected from its actuator and prevent the keys being operated without their values being registered.

, Again, when the locking device is automatic,it may be operated either'directly from the registering-wheels or the frame in which they are mounted; or it may be operated from an independent device, as the locking-bar J which looks the frame J For instance, where a locking-arm like the bell-crank arm 0 is employed, its front end may be made to engage the rear side of the frame J instead 7 of an arm of the locking-bar J so'that when the frame J 4 is lowered its rear end will lift the horizontal arm of the bell-crank and throw middles and front ends.

its lower end forward over the flange on the bar E as will be readily understood.

The remaining feature of my invention relates to the operating-keys. Heretofore in machines of this class the keys have usually consisted of simple levers fulcrumed between their ends, generally at a point between their This gave a short quick stroke to their front ends and a long and faster stroke to their rear ends, with a consequent loss of power in the work which their rear ends were required to do. In addition to the loss of power the very quick stroke of their rear ends was objectionable in many classes of machines.

Myimproved keys each consist of two levers P 1?, Figs. 1, 4, and 5, fulcrumed at their adjacent ends side by side upon a horizontal shaft P extending across the lower front side of the A tog gle composed of two links Q, Q is interposed between each lever P and a fixed point of the frame-work-in this instance a shaftQ extending across the lower part of the machine from one side frame to the other. The

central joint of this toggle is bent forward than it is later, and as the toggle becomesnearly straight the stroke of the lever P becomes very slow and powerful. This is especially advantageousin myimproved machine, for the resistance offered by the spring of the motor increases as the lever P and vibrating bar E rise, so that the slow and powerful stroke of the key is had when the spring has been put under greatest tension and ofiers the most resistance. This improved form of key, while perhaps peculiarly applicable to and advantageous in my machine, may be employed in many other styles of cash-registers.

There may be combined with the cent series of keys any of the well-known or suitable forms of stops or key-locks for the purpose of preventing the simultaneous operation of two or more keys of the series.

The machine is also provided with a keyarrester, which compels the full and complete stroke of the operated keys in each direction. A well-known form of such key-arrester and its combination with the operating-keys are illustrated in Fig. 1; but as its particular contruction and mode of operation form no part of my present invention it need notbe described.
